BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a structure combination or assembly, and more particularly to a structure assembly having a number of parts or elements to be secured together without additional fasteners and tools.

[0003] 2. Description of the Prior Art

[0004] Various kinds of typical structure assemblies, such as cabinets, tool boxes, room partitions, frameworks, wall assemblies, cases, desks, furniture structures, collapsible containers, etc. comprise a number of parts or elements to be secured or assembled together with fasteners and/or tools.

[0005] For example, U.S. Pat. No. 3,513,606 to Jones, and U.S. Pat. No. 4,638,614 to Wilcox disclose two of the typical structure assemblies which also comprise a number of parts or elements to be secured or assembled together with fasteners or bolts and/or tools. The users thus may have to prepare and purchase the fasteners or the bolts and/or the tools in order to secure or assemble the parts or elements together.

[0006] U.S. Pat. No. 4,065,220 to Ruga discloses another typical structure assembly which comprises a number of parts or elements to be secured or assembled together without fasteners or bolts and/or tools. However, the parts or elements are simply secured or assembled together with force-fitted engagements, and thus may not be solidly secured or retained together.

[0007] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional structure assemblies.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0027] Referring to the drawings, and initially to FIGS. 1-10, a structure assembly in accordance with the present invention comprises a number of erected or vertical ducts 21, 22 and a number of lateral or horizontal conduits 31 to be coupled or assembled together with a number of couplers 101, 103, so as to form a spatial frame device 1 that may include one or more parallelepiped frame units 10 formed therein.

[0028] For example, eight of the corner couplers 101 (as shown in FIG. 3) may be arranged in the eight corners of a parallelepiped frame unit 10, to couple four vertical ducts 21 or 22 and eight horizontal conduits 31 together, and to form the parallelepiped frame unit 10.

[0029] However, when the frame device 1 comprises two or more parallelepiped frame units 10 formed therein, as shown in FIGS. 1, 11, then four or more further couplers 103, such as the intermediate couplers 103 (as shown in FIG. 4) are further required to be provided and coupled between the horizontal conduits 31, in order to form the frame device 1 that includes two or more parallelepiped frame units 10 formed therein.

[0030] As shown in FIGS. 3, 4, each of the corner couplers 101 and the intermediate couplers 103 includes a vertical barrel 11 having a bore 13 formed therein, and having a peripheral flange 131 extended into the bore 13 thereof to form or define an aperture 14 therein which includes an inner diameter smaller than that of the bore 13 thereof. The bore 13 of the vertical barrel 11 includes an inner diameter slightly greater than, but preferably equals to the outer diameter of the vertical ducts 21, 22, in order to snugly receive the end portions 210 of the vertical ducts 21, 22, best shown in FIGS. 5, 8, and so as to allow the vertical ducts 21, 22 to be solidly coupled together by the vertical barrel 11 of the corner couplers 101 or the intermediate couplers 103.

[0031] One of the vertical ducts 21 or 22 includes a fastener 23 secured therein. For example, the fastener 23 includes a head 25 secured in the vertical duct 21, and includes a portion partially extended out of the vertical duct 21, to engage through the aperture 14 of the vertical barrel 11. The other vertical duct 22 includes a screw hole 24 formed therein, such as includes a lock nut 27 secured therein and having the screw hole 24 formed in the lock nut 27, to thread with the fastener 23, and thus to solidly couple the vertical duct 21, 22 to the vertical barrel 11.

[0032] Each of the corner couplers 101 and the intermediate couplers 103 includes two or more arms 12 extended outwardly or laterally from the vertical barrel 11. For example, each of the corner couplers 101 includes two arms 12 extended outwardly or laterally from the vertical barrel 11 (FIGS. 1, 3, 6, 11), and each of the intermediate couplers 103 includes three or more arms 12 extended outwardly or laterally from the vertical barrel 11 (FIGS. 1, 4, 11), to couple the horizontal conduits 31 together.

[0033] Each of the arms 12 includes a shank 15 extended therefrom and having an outer diameter slightly smaller than, but preferably equals to the inner diameter of the horizontal conduits 31, in order to snugly engage into the end portions or the bores 310 of the horizontal conduits 31, best shown in FIGS. 6, 8, and so as to allow the horizontal conduits 31 to be solidly coupled together by the arms 12 of the corner couplers 101 or the intermediate couplers 103.

[0034] Each of the arms 12 includes an outer diameter greater than that of the shank 15, but preferably equals to the outer diameter of the horizontal conduits 31, best shown in FIGS. 6, 8, for allowing the outer portions of the horizontal conduits 31 and the arms 12 to be flush with each other, and to form a smooth outer appearance.

[0035] Each of the shanks 15 of the arms 12 includes one or more, such as two opposite channels 16, 17 formed therein. Each of the horizontal conduits 31 includes one or more, such as two opposite ears 32, 33 extended therefrom, to engage into the channels 16, 17 of the shanks 15 respectively, and thus to further solidly secure the horizontal conduits 31 to the shanks 15 of the arms 12 respectively.

[0036] It is preferable that each of the ears 32, 33 of the horizontal conduits 31 includes a shape and/or a width and/or a depth and/or a height slightly smaller than, but preferably equals to that of the channels 16, 17 of the shanks 15 respectively, and thus to allow the horizontal conduits 31 to be further solidly secured to the shanks 15 of the arms 12 respectively by the snugly fitting or engagement of the ears 32, 33 in the channels 16, 17 of the shanks 15 respectively.

[0037] Each of the arms 12 may further include one or more, such as two opposite lock notches 18 formed therein, such as formed between the arm 12 and the shank 15 respectively, and communicating with the channels 16, 17 of the shanks 15 respectively, so as to form or define a coupling bar 181 between the arm 12 and the shank 15 respectively.

[0038] In operation, after the ears 32, 33 of the horizontal conduits 31 have been engaged into the respective channels 16, 17 of the shanks 15, and when the ears 32, 33 of the horizontal conduits 31 are aligned with the lock notches 18 of the arms 12, the ears 32, 33 of the horizontal conduits 31 may be engaged into the lock notches 18 of the arms 12 by rotating the horizontal conduits 31 relative to the arms 12 of the corner couplers 101 or the intermediate couplers 103 respectively (FIG. 7), so as to further solidly secure or couple the horizontal conduits 31 and the shanks 15 of the arms 12 together.

[0039] It is also preferable that the ears 32, 33 of the horizontal conduits 31 includes a thickness slightly smaller than, but preferably equals to the depth of the lock notches 18 of the arms 12 respectively, and thus to allow the horizontal conduits 31 to be further solidly secured to the arms 12 respectively by the snugly fitting or engagement of the ears 32, 33 in the lock notches 18 of the arms 12 respectively. The ears 32, 33 of the horizontal conduits 31 may be engaged with the coupling bar 181 of the arm 12 respectively, in order to limit the rotational movement of the horizontal conduits 31 relative to the arm 12.

[0040] Each of the corner couplers 101 and the intermediate couplers 103 may further include one or more levers 19 extended outwardly or laterally from the vertical barrel 11, and preferably arranged or located between the arms 12, to engage with and to support one or more plates 60, such as transparent or semi-transparent upper plates 60 between the horizontal conduits 31 by the levers 19.

[0041] Each of the levers 19 may further include an orifice 191 formed therein to receive a stud 41 of a sucker member 40 therein (FIGS. 1, 10), and to secure or support the sucker members 40 on the levers 19 respectively. The sucker members 40 may further be engaged with the plates 60, so as to further solidly support or retain the plates 60 between the horizontal conduits 31 by the levers 19 and the sucker members 40.

[0042] As shown in FIGS. 11, 12, the other plates 50, such as the metal or plastic or wood upper plates 50 may include a curved peripheral flange or skirt 51 extended or provided on the outer peripheral portion thereof, to engage with the horizontal conduits 31, and thus to allow the plates 50 to be secured or retained between the horizontal conduits 31 by the engagement between the curved skirts 51 of the plates 50 and the horizontal conduits 31, without the levers 19 and the sucker members 40.

[0043] As shown in FIGS. 1, 2, 9, the other glass or metal or plastic or wood side boards 61 may have four angle members 62 attached to the four corners thereof. For example, each of the angle members 62 may include a slot 63 formed therein to receive the corner portion of the boards 61, and may include two curved depressions 64 formed in the outer peripheral portion thereof to engage with the corresponding curved outer peripheral portions of the vertical ducts 21, 22 and the horizontal conduits 31, and thus for allowing the boards 61 to be secured and retained between the vertical ducts 21, 22 and the horizontal conduits 31 without fasteners or tools.

[0044] Referring again to FIGS. 1, 3, 4, 6, 8 and 11, each of the arms 12 may include one or more, such as two opposite cavities 121 formed in the upper and/or the lower portion thereof. The other angle members 71 may each include an axle 72 extended therefrom and rotatably engaged into the respective cavities 121 of the arms 12 respectively, and may each include a space 73 formed therein, to receive the corner portions 74 of a cover 70, and thus to rotatably secure the cover 70 to the corner couplers 101 and/or the intermediate couplers 103, and thus for allowing the cover 70 to be rotatably attached to the frame units 10 respectively.

[0045] Two of the angle members 62 may further be provided and engaged onto the other corner portions 75 of the cover 70 that are not pivotally or rotatably secured to the respective frame units 10 and that may be secured or retained between the vertical ducts 21, 22 and the horizontal conduits 31 by the angle members 62. A knob 77 may be attached to the cover 70 and arranged or located between the other corner portions 75 of the cover 70, in order to open and close the cover 70 relative to the frame units 10.

[0046] While forming or assembling the frame units 10 of the spatial frame device 1, the vertical ducts 21, 22 and the horizontal conduits 31 and the vertical barrel 11 are first assembled together by the corner couplers 101 and the intermediate couplers 103. The upper plates 50 or 60 may then be secured onto the horizontal conduits 31 either by the skirts 51 of the plates 50 or by the levers 19 and/or the sucker members 40. The side boards 61 may then be attached or retained between the vertical ducts 21, 22 and the horizontal conduits 31 by the angle members 62. The covers 70 may then be pivotally or rotatably attached to the corner couplers 101 and/or the intermediate couplers 103 by the other angle members 71.

[0047] Accordingly, the structure assembly in accordance with the present invention includes a number of parts or elements to be secured together without additional fasteners and tools.

[0048] Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed.
